The Republican presidential candidate will stop by on Thursday for his third appearance on the late-night series.

Donald Trump is returning to late night.

The Republican presidential candidate is set to appear on The Tonight Show Starring Jimmy Fallon on Thursday.

Trump's appearance, announced Monday, will come just days ahead of an appearance by his opponent, Hillary Clinton, who is scheduled to appear on Monday, Sept. 19.

Both candidates' Tonight Show visits come less that two weeks ahead of their first presidential debate on Monday, Sept. 26. The two shared the stage at NBC's Commander-in-Chief Forum, moderated by NBC's own Matt Lauer, last Wednesday.

This marks Trump's third time on Fallon's show overall, and his first visit in more than year. His last visit was Sept. 11, 2015. Other scheduled guests for Thursday's broadcast include Norm Macdonald and musical guest Kiiara.
